Market depth trader, mouse trading safety feature

I like the mouse trading function but would like to suggest a safety feature. A left (right) mouse click on the asks (bids) by oversight leads to an instant execution. In a liquid market that´s not a huge problem and maby favored, but imagine you are trading illiquid stocks with big spreads and an order book with big gaps. A small mistake will cost lots of money. My suggestion:

- only a left (right) DOUBLE click on a asklimit (bidlimit) places an buy(sell)order (this could be optional settable in the settings, especially for illiquid stocks etc.)
